Potable Water Tanks 700-700,000 Gallons

Coragated galvanized steel potable water tanks are among the most cost effective potable water storage available today.  CORGAL (corrugated galvanized) steel tanks are constructed of punched and rolled wall sheets that are bolted together at a project site.  Corgal potable water tanks are fitted with a geotextile pre-liner and a flexible membrane liner that comply with NSF-61 standards.  The CORGAL tank is constructed on a concrete foundation and not have a bottom structure. The NSF-61 compliant liner distributes the water load uniformly across the foundation area.
